Measuring Cardiac Autonomic Nervous System (ANS) Activity in Children
Published on: April 29, 2013
Abstract:
Systolic and diastolic blood pressure were measured in 1642 Swedish school children aged 12, 14, or 16 years. They represented 71% of all children in these age groups in the municipality where the investigation was done. The blood pressure was measured with an automatic, oscillometric blood pressure monitor. The systolic blood pressure increased significantly with age in both sexes. Boys aged 14 or 16 years had significantly higher systolic blood pressure than girls of the same ages.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
